The driven screw 302 is mechanically connected to the manual screw 102 through a transmission unit, so that the driven screw 302 and the manual screw 102 rotate synchronously; the manual screw 102 is also arranged with a driven gear 303, and the bottom of the driven gear 303 is connected to the driven gear 303. The driven rack group 304 and the driven rack group 304 are arranged at the tail end of the feeding frame 204; the transmission unit includes a worm wheel 305, a worm 306, and a synchronous shaft 307.
